IMPORTANT SAFETY INSTRUCTIONS
THIS MANUAL CONTAINS IMPORTANT INFORMATION REGARDING SAFETY, OPERATION,
MAINTENANCE AND STORAGE OF THIS PRODUCT. BEFORE USE, READ AND UNDERSTAND ALL
CAUTIONS, WARNINGS, INSTRUCTIONS AND PRODUCT LABELS, PLUS YOUR VEHICLE’S BATTERY
MANUFACTURER GUIDELINES. FAILURE TO DO SO COULD RESULT IN INJURY AND/OR PROPERTY
DAMAGE.
To ensure reliable service, your power inverter must be installed and used properly. Please read the installation
and operating instructions thoroughly prior to installation and use. Pay particular attention to the WARNING
and CAUTION statements in this manual. The CAUTION statements advise against certain conditions and
practices that may result in damage to your inverter. The WARNING statements identify conditions or practices
that may result in personal injury. Read All Instructions Before Using This Power Inverter!
WARNINGS
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, EXPLOSION OR INJURY
1. Do not connect to AC distribution wiring. This inverter is NOT grid interactive.
2. Remove appliance plug from outlet strip or turn off inverter before working on the appliance. Multiple
outlet power strips with switches and circuit breakers only interrupt power to the “hot” receptacle
terminals. For SSW-350-12A & SSW-600-12A, the “Neutral” terminals remain powered with respect to
the “Ground” terminals.
3. Do not make any electrical connections or disconnections in areas designated as IGNITION PROTECTED.
This includes 12 V DC cigarette plug connections, and terminal connections.
4. This is not a toy - keep away from children.
5. DO NOT install object into air vents.
CAUTIONS
1. The chassis and the input Negative terminal of the inverter are internally connected to the AC Ground.
Hence, the input Negative terminal should be used as the grounding terminal. Do not use with Positive
Grounded Electrical Systems (the majority of modern automobiles, RVs, trucks and boats are Negative
Grounded Electrical Systems).
2. Observe correct polarity when connecting the DC input terminals of the inverter to the battery. Connect
Positive of the battery to the Positive input connector of the inverter and the Negative of the battery to
the Negative input terminal of the inverter. Reverse polarity connection will result in a blown fuse and
may cause permanent damage to the inverter. Damage due to reverse polarity is not covered under
warranty.
3. This inverter will not operate high wattage appliances that exceed the output power limit or the surge
power limit.
4. For SSW-350-12A & SSW-600-12A, grounding the Neutral will cause the inverter to shut down. Hence,
do not connect the Neutral of the AC output receptacles to Ground.
5. Do not operate this inverter if it is wet.
6. Do not install in engine compartment – please install in a well ventilated area.
7. This inverter is not tested for use with medical devices.

IMPORTANT SAFETY INSTRUCTIONS
IMPORTANT WIRING INFORMATION
Substantial power loss and reduced battery operating time results from inverters installed with wires that are
not sized correctly based on the length and the current required to be carried. Current flowing through a wire
produces voltage drop along its length due to the resistance of the wire and due to the value of the current
carried through it. The resistance of the wire is inversely proportional to the cross-sectional area of the wire
(designated in mm2 or AWG) and directly proportional to its length i.e. thinner and longer wire has higher
resistance and hence, produces higher voltage drop. Similarly, thicker and shorter wire has lower resistance and
hence, produces lower voltage drop. Hence, symptoms of low DC input voltage / battery power can result from
wires that are either excessively long or have an insufficient cross-sectional area (designated in mm2 or AWG).
The wires should be sized based on the maximum current they are required to carry and the distance between
the battery and the inverter to limit the voltage drop to 2% to 5%.
Wires are rated based on its insulation, temperature and operating environment. Please ensure that the wire
insulation is of the appropriate type for the operating environment.
The installer/operator should be especially aware of the requirements to maintain secure, tight, water-resistant
electrical connections and to provide for strain relief for DC wires and appliance wiring.

PRINCIPLE OF OPERATION
The inverter converts power in two stages. The first stage is a DC to DC conversion process that raises the
low voltage DC at the inverter input to high voltage DC of approximately 150 VDC. The second stage is the
actual inverter stage that converts the high voltage DC into nominal 115 VAC, 60 Hz AC (RMS). The DC-toDC converter stage uses modern high frequency power conversion techniques that have replaced the bulky
transformers found in less technologically-advanced models. The inverter stage uses advanced power MOSFET
transistors in a high frequency full bridge configuration.
THE OUTPUT WAVEFORM
The AC output waveform of the SSW-series inverter is known as “Pure Sine Wave” or “True Sine Wave”. It is a
waveform that has characteristics same to the sine wave shape of utility power (See Fig. 1).

INSTALLATION / ENVIRONMENTS
DC POWER SOURCE REQUIREMENTS
The DC power source must provide between 10.5 and 15.5 Volts DC and must be able to supply the necessary
current to operate the load. The power source may be a battery or a well-regulated DC power supply. To
obtain a rough estimate of the current (in Amperes) the power source must deliver, simply divide the power
consumption of the load (in Watts AC) by 10.
Example: if a load is rated at 100 Watts AC, the DC power source must be able to deliver: 100 / 10 = 10A.
The inverter will provide you nominal 115 VAC when powered by a 12 VDC source such as is found in a vehicle
or multiple battery configurations as shown in Fig. 2. This manual does not describe all of the possible types of
battery configurations, battery charging configurations and battery isolation configurations.
For normal operation of the inverter, the DC power source must provide between 11.0 and 15.0 VDC and the
required current. This DC power source must be a well-regulated DC power supply or alternator and deep
cycle battery system typically found in vehicles and marine crafts. The DC power source may also be two or
more 12 volt batteries connected in parallel. On larger applications, the power source may be several batteries
connected in parallel as shown in Fig. 2.

INSTALLATION NOTES
WARNING: Ensure ventilation when using batteries. Batteries may generate flammable gas during
charging or discharging.
The inverter (350 W to 2000 W models) has four slots in its mounting bracket that allow the unit to be fastened
against a bulkhead, floor, wall or other flat surface. Ideally, the mounting surface should be cool to the touch.
It is more electrically efficient to use longer AC wiring than DC wiring, so install the inverter as close as
possible to the 12 VDC power source.

INSTALLATION / ENVIRONMENTS
The inverter can be operated in any position, however, if it is to be mounted on a wall, mount it horizontally
(Fig 3a) so that indicators, switches, outlets and terminal blocks located on the front panel are visible and
accessible. Do not mount on wall in positions shown in Figs. 3 (b) & 3(c). If the inverter is to be installed in a
moving vehicle, we strongly recommend that the inverter be shock-mounted either on the floor (in a clear, safe
area) or on a secure flat surface
(Fig 3a)

(c)
Fig. 3 Mounting arrangement on wall
CAUTION
The power inverter must be connected only to batteries with a nominal output voltage of 12 V. The unit will
not operate from a 6 Volt battery, and will sustain permanent damage if connected to a 24 V battery.
CAUTION
Loose connectors may cause overheated wires and melted insulation. Check to make sure you have not
reversed the polarity. Reverse polarity connection will result in a blown fuse and may cause permanent damage
to the inverter. Damage due to reverse polarity is not covered by warranty.
CONNECTING TO A DC POWER SOURCE
Please ensure that the DC side wires and external fuses are selected as given below.
Note that an external fuse is required to protect the battery wires from short circuit. A battery is an unlimited
source of current and can deliver extremely high (up to 10,000 A of current) into a short circuit that will melt
the wires and cause fire hazard.
Current limiting fuse with Ampere Interrupting Capacity (AIC) of 10000 A or more or Class T fuse is, therefore,
recommended.

5. Switch on the inverter. Wait for a few seconds
6. The green LED indicator will be lighted to indicate that the inverter is functioning
7. Switch on the load(s)
The inverter is engineered to be connected directly to standard electrical and electronic equipment in the
manner described above. Do not connect the power inverter to household or RV AC distribution wiring. Do
not connect the power inverter to any AC load circuit in which the Neutral conductor is connected to Ground
(Earth) or to the Negative of the DC (battery) source.
WARNING: Do not connect directly to AC distribution wiring. This inverter is NOT grid interactive.
OPERATING ENVIRONMENT
For best operating results, the inverter should be placed on flat surface, such as the ground, car floor, or other
solid surface. The power cord allows easy positioning of the inverter. The inverter should only be used in
locations that meet the following criteria:
DRY
Do not allow water and/or other liquids to come into contact with the power inverter. In all marine
applications, do not install the inverter below or near the waterline and keep the inverter away from moisture
or water.
COOL
Ambient air temperature should be between 30 degrees F (-1 degree C) non-condensing, and 105 degrees F (40
degrees C). Do not place the inverter on or near a heating vent or any piece of equipment which is generating
heat above room temperature. Keep the inverter away from direct sunlight, if at all possible.
VENTILATED
The unit is cooled by load controlled fan (s). The fan(s) will be normally switched off at low loads to conserve
battery power and will be switched on automatically once the load reaches a certain threshold. Keep the area
surrounding the inverter clear to ensure free air circulation around the unit. Do not place items on or over
the inverter during operation. An additional external fan is helpful if the inverter is operating at maximum
power outputs for extended periods of time. The unit will shut down if the internal temperature exceeds the
operating temperatures. The unit will restart after it cools.
SAFE
Do not use the inverter near flammable materials or in any locations that may accumulate flammable fumes of
gases.

OPERATING TIPS
RATED VERSUS ACTUAL CURRENT DRAW OF EQUIPMENT
Most electrical tools, appliances and audio/video equipment have labels that indicate the power consumption
in Amps or Watts. Be sure that the power consumption of the item you wish to operate is less than inverter’s
power. (If the power consumption is rated in Amps AC, simply multiply by the AC Volts (115) to determine the
approximate Wattage). The inverter will shut down if it is overloaded. The overload must be removed before
the inverter will restart. Resistive loads are the easiest for the inverter to run. However, larger resistive loads,
such as electric stoves or heaters, usually require more wattage than the inverter can deliver. Inductive loads,
such as TV’s and stereos, require more current to operate than do resistive loads of the same wattage rating.
Induction motors, as well as some televisions, may require 2 to 6 times their wattage rating to start up. The
most demanding in this category are those that start under load, such as compressors and pumps. To restart the
unit after a shutdown due to overloading, remove the overload if necessary turn the power switch OFF, wait
for at least 3 minutes and then switch ON again.
SIZING CHART FOR TYPICAL LOADS THAT REQUIRE HIGH STARTING SURGE
The manufacturers’ specifications of the appliances and devices indicate only the running power required.
The surge power required by some specific types of devices has to be checked with the manufacturer, actually
tested or guessed at best.
The Table below lists some common loads that require high surge power on start up. A “Sizing Factor” has
been recommended against each which is a Multiplication Factor to be applied to the rated running Watt
rating of the load to arrive at the continuous power rating of the inverter (Multiply the running Watts of the
device / appliance by the Sizing Factor).

OPERATING TIPS
DETERMINING BATTERY SIZE
The power inverter will require DEEP CYCLE lead acid batteries of appropriate capacity.
The automotive SLI (Starting/lighting/Ignition) battery is not designed for repeated deep discharge. The SLI
battery may not supply enough energy and its service life may be reduced.
To determine the minimum battery size that you will need to operate appliances, follow these steps:
1. Determine the AC wattage of each appliance and / or tool you will need to simultaneously operate from
the inverter. To do this, read the labels on the equipment to be operated. Usually, power consumption is
shown in Watts. If it is shown in Amps, multiply by 115 to determine the AC wattage.
2. For each appliance, estimate the number of hours the appliance will be in use between battery
recharges.
3. For each appliance, determine the Watt-Hours of energy required by multiplying the AC wattage by the
number of hours of use.
4. Add the Watt-Hours of energy for each appliance to get the total Watt-Hours of energy for all
appliances to be used.
5. Divide the total Watt-Hours of energy on the AC side by 10 to get the total Ampere-Hour of energy on
the 12 VDC side to support the operation of the appliances.
6. The Ampere-Hour (AH) capacity of the battery should be 2 times the total Ampere-Hour energy required
on the 12 VDC side to support the operation of the devices (as calculated at step 5 above). Two times
factor is necessary because batteries are normally not discharged below 50% capacity.
To get an estimate of the current (in Amps) that the battery is delivering, divide the load's AC consumption
power (in Watts) by (10).
Keep in mind that most appliances are not operating for long periods of time. For example, a typical homeuse coffee maker draws 500 Watts during its brew time of 5 minutes, but it maintains the temperature of the
pot at about 100 Watts. Typical use of a microwave is only for a few minutes, sometimes at low power. Some
exceptions to brief operating times are TVs, computers etc.
In most instances, the inverter can be left connected to the battery when not in use, make sure power switch is
in the OFF position.
Battery performance drops in low temperature environment. Higher capacity batteries should be installed if
the environmental temperature is below 20oC.

PROTECTIVE FEATURES OF THE INVERTER
OVER TEMPERATURE PROTECTION
The unit is cooled by load controlled fan (s). The fan(s) will be normally switched off at low loads to conserve
battery power and will be switched on automatically once the load reaches a certain threshold. In case the fan
fails or if the cooling is inadequate due to higher ambient temperature or restricted air flow, the temperature
inside the inverter will be too high and the unit will automatically shut down. Allow the unit to cool for at
least 15 minutes before restarting after a heat-related shutdown. Unplug unit while cooling.
LOW BATTERY VOLTAGE PROTECTION
This condition is not harmful to the inverter but could damage the power source. The inverter automatically
shuts down when input voltage drops to 10.5 Volts.
OVER VOLTAGE PROTECTION
The inverter will automatically shut down when the input voltage exceeds 15.3 Volts DC. Input voltage
exceeding 16 Volts could damage the inverter.
OVERLOAD PROTECTION
The inverter will automatically shut down when the continuous draw exceeds rated Watts.
SHORT CIRCUIT PROTECTION
The inverter will shut down. Remove the short circuit and restart inverter.
EARTH FAULT PROTECTION
This inverter complies with the standard current leakage allowance. When large current leakage to earth
terminal occurs, the protection circuit activates and shuts down the inverter, which prevents electric shock to
humans. Turn OFF the inverter, unplug the fault AC appliance and then turn ON is the only way to restart it.
The 1000, 1500 and 2000 W models are provided with a GFCI that will trip in case of any leakage on the load
side. The GFCI will be required to be reset
LOW INPUT VOLTAGE ALARM
An alarm will sound when the voltage at the input terminals of the inverter drops to 11.0 Volts. This is an
indication that either the battery terminal voltage has dropped due to its discharged condition and needs to
be re-charged OR there is an excessive voltage drop across the wires connecting the inverter to the battery
(due to use of thinner and longer length of wires that will produce higher voltage drop at higher loads OR due
to loose connections). The user should stop operation of the electronic device at this time since the inverter will
shut down automatically shortly thereafter, when the input voltage at the inverter further drops to 10.5 Volts.
In case the alarm is due to the discharged condition of the battery, start your engine to recharge the battery /
use an appropriate battery charger.
If the low voltage alarm sounds when the battery is fully charged, follow the steps for solving lack of output
power in the Troubleshooting Guide at page 14.
NOTE: It is normal for the alarm to sound while the unit is being connected to or disconnected from
the power source. This is not indicative of a problem.

Warranty
2 YEAR Limited Warranty
The Samlex SSW Series Inverters manufactured by Samlex America, Inc. (the “Warrantor“) are warranted to be
free from defects in workmanship and materials under normal use and service. This warranty is in effect from
the date of purchase by the user (the “Purchaser“).
For a warranty claim, the Purchaser should contact the place of purchase to obtain a Return Authorization
Number. The defective part or unit should be returned at the Purchaser’s expense to the authorized location.
A written statement describing the nature of the defect, the date of purchase, the place of purchase, and the
Purchaser’s name, address and telephone number should also be included.
If upon the Warrantor’s examination, the defect proves to be the result of defective material or workmanship,
the equipment will be repaired or replaced at the Warrantor’s option without charge, and returned to the
Purchaser at the Warrantor’s expense.
No refund of the purchase price will be granted to the Purchaser, unless the Warrantor is unable to remedy the
defect after having a reasonable number of opportunities to do so.
Warranty service shall be performed only by the Warrantor. Any attempt to remedy the defect by anyone other
than the Warrantor shall render this warranty void.
There shall be no warranty for defects or damages caused by faulty installation or hook-up, abuse or misuse of
the equipment including exposure to excessive heat, salt or fresh water spray, or water immersion.
No other express warranty is hereby given and there are no warranties which extend beyond those described
herein. This warranty is expressly in lieu of any other expressed or implied warranties, including any implied
warranty of merchantability, fitness for the ordinary purposes for which such goods are used, or fitness for a
particular purpose, or any other obligations on the part of the Warrantor or its employees and representatives.
DISCLAIMER OF LIABILITY
There shall be no responsibility or liability whatsoever on the part of the Warrantor or its employees and
representatives for injury to any persons, or damage to person or persons, or damage to property, or loss
of income or profit, or any other consequential or resulting damage which may be claimed to have been
incurred through the use or sale of the equipment, including any possible failure of malfunction of the
equipment, or part thereof.
The Warrantor assumes no liability for incidental or consequential damages of any kind.
